Need every unit at once?

The all-in-one time unit converter lets you pick any source and target unit in a single tool.

Each converter takes one time unit and converts it into all the others — seconds, minutes, hours, days, weeks, months, and years — with a live calculator, the exact conversion formulas, a reference table, and real-world examples. Just choose the unit you are starting from.

Conversions between seconds, minutes, hours, days, and weeks are exact. Months use the average length of 30.44 days and years use the Julian year of 365.25 days, which averages in the extra day from leap years. For the difference between two specific calendar dates, use a date difference calculator instead.
